In broadcasting, a commercial bumper, ident bumper or break-bumper (often shortened to bump) is a brief announcement, usually two to 15 seconds in length that can contain a voice over, placed between a pause in the program and its commercial break, and vice versa. The host, the program announcer or a continuity announcer states the title (if any) of the presentation, the name of the program, and the broadcast or cable network, though not necessarily in that order. On children's television networks, they are sometimes called external eyecatches due to the resemblance of internal eyecatches in anime and there is usually no voice over, but some bumpers do feature one. Bumper music, often a recurring signature or theme music segment, is nearly always featured. Bumpers can vary from simple text to short films.
